Hydrogen is the energy medium for fuel cell automobiles. The hydrogen used in the fuel cell reacts with oxygen to yield water. Until now, the world’s hydrogen requirements have been largely fulfilled by the reformation of steam from
natural gas. Since this hydrogen production process still gives rise to CO2 emissions as a result of the carbon content of the natural gas, appropriate economically viable processes for hydrogen production from renewable sources must be developed. 3
Hydrogen generated by this means is the fuel of the future, which in combination with the fuel cell ensures mobility free of pollutants and CO2. Environment-friendly hydrogen production processes include electrolysis using
electricity generated from renewable sources (at hydroelectric, wind, solar or geothermal power plants) and the gasification of biomass.
